Tell your prescriber or health care professional about all other medicines you are taking, including non-prescription medicines, nutritional supplements, or herbal products. Also tell your prescriber or health care professional if you are a frequent user of drinks with caffeine or alcohol, if you smoke, or if you use illegal drugs. These may affect the way your medicine works. Check with your health care professional before stopping or starting any of your medicines.

What should I watch for while taking anistreplase?

You will be closely monitored to check your progress after you have received anistreplase. Follow your prescriber's advice exactly; you may need bed rest to minimize the risk of bleeding.

Anistreplase can make you bleed more freely; this effect can last for several days. Try to avoid damage to your teeth and gums when you brush or floss your teeth, and to avoid any other injury to yourself.

Do not take aspirin, ibuprofen, or other nonprescription pain relievers during or for several days after anistreplase treatment unless otherwise instructed by your prescriber or health care professional.

You may feel dizzy or lightheaded. To avoid the risk of dizzy or fainting spells, sit or stand up slowly, especially if you are an older patient.

What side effects may I notice from receiving anistreplase?

Side effects that you should report to your prescriber or health care professional as soon as possible:

blood in the urine, stools, or vomit

chest pain or tightness

difficulty breathing, wheezing

fever

severe headache

skin rash, itching

slow or fast heart rate

swelling of your face, lips, or tongue (rare)

unusual bleeding, bruising, or purple spots on the skin

unusual swelling

Side effects that usually do not require medical attention (report to your prescriber or health care professional if they continue or are bothersome):

dizziness, lightheadedness

nausea, vomiting

Where can I keep my medicine?
